My experience for what it's worth. I read that the Hub One was pants but that the BT HH6 could be used with Plusnet and was superior.
While waiting for my connection to go live, I bought two. The standard HH6 and the Business HH6. I found that the HH6s were slightly better with wifi but found to my surprise that they connected consistently 5 or 6Mbps less than the Hub One.
As the wifi with the Hub One was more than adequate in my house for my purposes I chose the better connection speed of the Hub One.
Perhaps there has been a firmware update since the bad reports I read of the Hub One.
Mine says: Plusnet Hub One | Software version 126.96.36.199.83.8.259 | Last updated Unknown
